NASHUA, N.H. -- Barack Obama is telling his supporters they're "the wave" and he's "riding it."
Obama is basking in his new front-runner status in Tuesday's New Hampshire primary.
Rival Democrat Hillary Clinton, meanwhile, is telling her supporters her quest for the White House isn't just political, it's personal. At a meeting with undecided voters, one person asked how she keeps going.
The New York senator replied, "It's not easy."
Democrat John Edwards, who is snugly in third place in the New Hampshire polls, is showing no signs of slowing down.
He gave speeches every couple of hours on an all-night bus tour of the Granite State. He swiped at Clinton, saying she is the candidate who has taken the most money from the drug companies.
